5 Surprising Facts About St. Patrick’s Day
St. Patrick’s Day, celebrated on March 17 each year, is known for its parades, shamrocks, and a whole lot of green. It’s a day when people around the world embrace Irish culture — whether they have Irish heritage or not. But behind all the revelry, St. Patrick’s Day has a deep and fascinating history that goes far beyond the modern celebrations. Some of the traditions we associate with March 17th aren’t as old as you’d think, while others have surprising historical roots. Here are five intriguing facts about St. Patrick’s Day that might just change the way you see this beloved holiday.
Pubs Were Closed on St. Patrick’s Day
Long before it became a worldwide celebration filled with traditional food, music, and pints of Guinness, St. Patrick’s Day was a quiet and solemn religious feast day in Ireland. For centuries, March 17 was dedicated to honoring St. Patrick’s role in bringing Christianity to Ireland, and the day was primarily observed through prayer, church services, and reflection. In fact, until the 1970s, Irish law required pubs to close on March 17 to preserve the day’s religious significance.
It wasn’t until later in the 20th century that the holiday evolved into a more public and festive occasion. As Ireland sought to promote its culture and boost tourism, St. Patrick’s Day’s celebratory aspects became more prominent. Today, while the religious roots remain, St. Patrick’s Day is as much a celebration of Irish heritage and national pride as it is a tribute to the country’s patron saint.

St. Patrick Wasn’t Irish — And His Name Wasn’t Patrick
One of the most surprising facts about St. Patrick’s Day is that the eponymous saint wasn’t actually Irish. He was born in Roman Britain, likely in the late fourth century, to a well-off family. His birth name was likely Maewyn Succat, though legend says he later changed it to Patricius, or Patrick, from the Latin word for “nobleman.” His father was a deacon, and his grandfather was a priest, but Patrick wasn’t particularly religious in his youth.
That changed when, as a teenager, he was kidnapped by Irish raiders and taken to Ireland, where he was enslaved for several years. Forced to work as a shepherd, Patrick endured harsh conditions and turned to prayer for solace, eventually escaping and returning to Britain. Years later, after training as a cleric, he returned to Ireland as a missionary, determined to spread Christianity. He is now regarded as the country’s patron saint, even though he wasn’t originally from there.
Blue Was Originally Associated With St. Patrick
Although green is now synonymous with St. Patrick’s Day, the color historically associated with Ireland’s patron saint was actually blue. In early Irish history, a shade known as "St. Patrick’s Blue" appeared in ancient manuscripts and on the robes of Irish kings. Later, it became the official color of the Order of St. Patrick, an 18th-century chivalric order whose knights wore sky-blue cloaks.
Green only became linked to the holiday in the 18th and 19th centuries, largely due to Ireland’s nickname, the “Emerald Isle," and the growing significance of the shamrock, which, according to legend, St. Patrick used to explain the concept of the Holy Trinity. During the Irish Rebellion of 1798, wearing green became a symbol of Irish nationalism, cementing the color’s association with St. Patrick and Ireland in general.
St. Patrick Didn’t Drive Snakes Out of Ireland
The story of St. Patrick driving all the snakes out of Ireland is one of the most famous legends about the historical figure, but there’s just one problem: Ireland never had any snakes to begin with. Since the last Ice Age, the island has been too cold and too isolated for snakes to survive, making it one of the few places in the world naturally free of them. Most historians believe the “snakes” in the legend symbolize the pagan traditions and beliefs that Patrick worked to replace with Christian teachings, particularly the influence of the Druids, who held significant religious and political power in pre-Christian Ireland.
While he may not have actually driven out any real snakes, St. Patrick’s influence, and his efforts to convert the Irish, played a key role in shaping the country's spiritual identity. Still, the image of him heroically chasing away serpents makes for a much more dramatic story and served as a way of explaining the lack of snakes on the island — a legend that has endured for centuries.
The First St. Patrick’s Day Parade Was in America, Not Ireland
Many people assume that St. Patrick’s Day parades originated in Ireland, but the first recorded parade actually took place in the United States. On March 17, 1601, in what is now St. Augustine, Florida, Spanish settlers and Irish clergy organized the first known St. Patrick’s Day celebration. The St. Patrick’s Day parades in the U.S. Northeast are perhaps better known, however. Boston hosted its first parade in 1737, followed by New York City in 1762, when Irish soldiers serving in the British army marched through the streets to honor their homeland.
These early parades set the stage for what became a major tradition in Irish American communities. When Irish immigrants arrived in the U.S. during the 19th century, especially in the years after the Great Famine, St. Patrick’s Day parades became a way of expressing their cultural pride and solidarity. Ireland, however, didn’t hold its first official St. Patrick’s Day parade until 1903, when the day became a public holiday.
